Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nanotube production, in particular to a folding nanotube production collector. Background Art
[0002] Carbon nanotubes are one-dimensional quantum materials with a special structure (radial dimension in the nanometer range, axial dimension in the micrometer range, and both ends of the tube are basically sealed). Carbon nanotubes are composed of several to dozens of coaxial circular tubes formed by carbon atoms arranged in a hexagonal pattern, and a fixed distance is maintained between layers. Carbon nanotubes are light in weight, with a perfect connection of the hexagonal structure, and have many exceptional mechanical, electrical, and chemical properties. In recent years, with the in-depth research on carbon nanotubes and nanomaterials, their broad application prospects have been continuously demonstrated.
[0003] The main preparation method of carbon nanotubes is chemical vapor deposition. Carbon nanotubes are light in weight, conductive, heat-conductive, and have a certain viscosity. In traditional processes, for carbon nanotubes grown on a silicon wafer substrate, they are usually collected by manual scraping. Such a collection method not only requires a lot of manpower and time, but also the collected carbon nanotubes are prone to entanglement, which affects subsequent use.

[0037] For a better explanation of the present utility model for easy understanding, the following will describe the present utility model in detail with reference to the accompanying drawings through specific embodiments.
[0038] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, the directional indications will also change accordingly.
[0039] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically and clearly defined.
[0040] In the present utility model, unless otherwise clearly specified and defined, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; "connection" can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0041] See Figure 1 、 Figure 2 and Figure 4 As shown in, the present utility model provides a foldable nanotube production collector, which specifically includes a housing 1, a folding mechanism 2, a catalyst feeding mechanism 3, and an air inlet pipe 4. Among them, a discharge port is provided on the housing 1. Specifically, the housing 1 can preferably be a circular tube or a square tube, and can preferably be vertically arranged. The discharge port is located at the lower end of the housing 1, and the gas to be discharged can also flow through the discharge port. The folding mechanism 2 includes a driving component 23, a mounting shaft 22 arranged in the housing 1, and a pair of bearing plates 21. The bearing plates 21 are all sleeved on the mounting shaft 22. The driving component 23 can drive the bearing plates 21 to deflect based on the mounting shaft 22, so that the pair of bearing plates 21 can be folded or spliced with each other. Moreover, when the bearing plates 21 are in a horizontal state, the pair of bearing plates 21 are spliced into a flat plate and can block the inner wall of the housing 1. The spliced flat plate can preferably be a circular plate or a square plate corresponding to the cross-sectional shape of the housing 1.
[0042] The catalyst feeding mechanism 3 can penetrate through the housing 1 to convey the catalyst onto the bearing plate 21 for facilitating the replenishment of the catalyst. The catalyst can accumulate on the bearing plate 21 for preparing nanotubes. The gas inlet pipe 4 is communicated into the housing 1 to be able to introduce inert gas, reducing gas and reaction carbon source gas into the housing 1. Among them, the inert gas can be argon or helium, etc., and preferably argon; the reducing gas is hydrogen, and the reaction carbon source gas is any one of acetylene, methane, carbon monoxide, ethylene, etc. In addition, a heating mechanism (not shown) for providing heat source is arranged outside the housing 1 to enable the reaction temperature in the housing 1 to be 600-900 °C, so that the preparation of nanotubes can proceed smoothly.
[0043] This device is applicable to the reaction and collection of nanotubes (for example, carbon nanotubes). The specific reaction conditions are: the temperature is 600-900 °C; hydrogen and acetylene are introduced into an argon atmosphere. After reaching the reaction conditions, the catalyst falls from the upper catalyst feeding mechanism 3 through the top wall of the housing 1 onto the flat plate formed by splicing the paired bearing plates 21 (see Figure 1 , Figure 5 and Figure 6 ), and accumulates on the flat plate. The gas inlet pipe 4 directly provides the gas carbon source into the housing 1. When in an argon environment, the gas carbon source will crack into carbon atoms, and then deposit carbon nanotubes on the catalyst. After the reaction is completed, the driving assembly 23 can drive the bearing plate 21 to deflect based on the mounting shaft 22, so that the paired bearing plates 21 can be folded with each other (see Figure 2 ), and the carbon nanotubes on the bearing plate 21 naturally fall due to the action of gravity and can be collected at the lower end of the housing 1. This collection method is very convenient and does not require too much manual intervention, thus can also greatly improve the preparation and collection efficiency of carbon nanotubes, which well meets the development needs of the nanotube industry. It should be noted that even if there is a small amount of carbon nanotubes remaining on the bearing plate 21, it will not affect the subsequent preparation of carbon nanotubes. After the carbon nanotubes fall, the driving assembly 23 can drive the bearing plate 21 to deflect in the reverse direction based on the mounting shaft 22, so that the paired bearing plates 21 can return to the horizontal state and be spliced with each other again (see Figure 1 ), and the catalyst powder falling from above continues to accumulate on the flat plate formed by splicing the paired bearing plates 21, and carbon nanotubes can be continuously prepared.
[0044] In a preferred embodiment, see Figure 5 and Figure 6, the carrier plate 21 includes a semi-circular flat plate 211 and a mounting portion 212 formed on the straight edge of the semi-circular flat plate 211. A socket hole adapted to the mounting shaft 22 is provided in the mounting portion 212; the paired carrier plates 21 can be spliced with each other into a circular flat plate to block the circular cross-section of the housing 1, thereby preventing the catalyst from falling from the edge of the flat plate. The two mounting portions 212 are adjacent to each other along the axial direction on the mounting shaft 22. See Figure 5 , after the two carrier plates 21 are spliced, the edge contour of the mounting portion 212 forms a broken line on the flat plate, and the socket holes in the two mounting portions 212 are coaxially arranged, so that they can be sleeved on the mounting shaft 22 together, enabling the two carrier plates 21 to fold and splice with each other.
[0045] See again Figure 6 , the driving assembly 23 includes a hinge seat 231, a connecting rod 232, a push rod 233 and a guide sleeve 234. The hinge seat 231 is arranged on the carrier plate 21 (a hinge seat 231 and a connecting rod 232 are arranged on each carrier plate 21). One end of the connecting rod 232 is hinged to the hinge seat 231 and the other end is hinged to the first end of the push rod 233. The guide sleeve 234 is sleeved on the push rod 233. Among them, the guide sleeve 234 can be installed on the inner wall of the housing 1 through an auxiliary bracket (not shown) to limit and guide the running direction of the push rod 233. The second end of the push rod 233 can penetrate the housing 1 and be connected to an external motor assembly (not shown). The motor assembly can include a motor and a gear-rack set, or include a motor and a worm and worm gear set, so as to drive the push rod 233 to perform a linear reciprocating motion. The dynamic seal is provided between the bottom of the housing 1 and the push rod 233, which can not only maintain the sealing effect but also does not interfere with the movement of the push rod 233. When the push rod 233 reciprocates up and down in the vertical direction under the action of the motor assembly, it can drive the carrier plate 21 to deflect based on the mounting shaft 22 through the connecting rod 232. For example, see Figure 2 , when the push rod 233 moves down along the guide sleeve 234, it will pull the connecting rod 232 down, and then drive the hinge seat 231 to move down and approach each other, thereby realizing the mutual folding of the carrier plates 21; see Figure 1 , when the push rod 233 moves up along the guide sleeve 234, it will push the connecting rod 232 up, and then drive the hinge seat 231 to move up and move away from each other, thereby realizing the mutual splicing of the carrier plates 21. In addition, it should be noted that in other embodiments, the driving assembly 23 can also adopt other similar structures as long as it can realize the folding and splicing actions of the carrier plate 21.
[0046] In a preferred embodiment, the foldable nanotube production collector further includes a collection box 5. The collection box 5 is docked to the discharge port at the lower end of the housing 1. The collection box 5 can collect the fallen carbon nanotubes. An air outlet pipe 51 is provided on the collection box 5. There is only one air outlet pipe 51. Argon gas is continuously introduced through the air inlet pipe 4, and the excess gas is discharged from the air outlet pipe 51 to ensure a stable air pressure in the argon gas atmosphere.
[0047] For the convenience of arranging each structure, an inclined connecting pipe 11 is formed at the discharge port of the housing 1. The collection box 5 is docked to the lower end of the connecting pipe 11. An air outlet pipe 51 is provided at the top of the collection box 5. Among them, flange edges can be formed at the docking positions between the collection box 5 and the connecting pipe 11. The collection box 5 and the connecting pipe 11 are detachably connected by a clamp or a plurality of buckles. Specifically, it can be that the clamp surrounds and wraps the butt joint flange edge, or it can also be that a plurality of buckles on the collection box 5 can buckle the flange edge on the connecting pipe 11, so that the collection box 5 and the connecting pipe 11 are detachably connected, and thus the collection box 5 can be conveniently replaced.
[0048] Further, referring to Figure 1 , the end of the air inlet pipe 4 is docked to the air inlet at the middle part of the housing 1; or, referring to Figure 3 , the air inlet pipe 4a penetrates through the air inlet at the upper part of the housing 1 and extends along the inner wall of the housing 1 to the middle part of the housing 1, so that the air outlet position of the air inlet pipe 4 is close to the catalyst accumulated on the carrier plate 21, thereby being able to improve the production efficiency of the nanotubes. Among them, in actual production, different arrangement methods of the air inlet pipe 4 can be selected according to requirements.
[0049] In addition, the catalyst feeding mechanism 3 includes a hopper 31 and a material guiding pipe 32. The hopper 31 is located outside the housing 1. The bottom of the hopper 31 is connected to the material guiding pipe 32. The material guiding pipe 32 penetrates through the top wall of the housing 1 to be able to convey the catalyst onto the carrier plate 21 to meet the production requirements of the carbon nanotubes.
